## Arrays: Left Rotation

Check out the resources on the page's right side to learn more about arrays. The video tutorial is by Gayle Laakmann McDowell, author of the best-selling interview book Cracking the Coding Interview.

A *left rotation* operation on an array of size shifts each of the array's elements unit to the left. For example, if left rotations are performed on array , then the array would become .

Given an array of integers and a number, , perform left rotations on the array. Then print the updated array as a single line of space-separated integers.

**Input Format**

The first line contains two space-separated integers denoting the respective values of (the number of integers) and (the number of left rotations you must perform).

The second line contains space-separated integers describing the respective elements of the array's initial state.

**Constraints**

**Output Format**

Print a single line of space-separated integers denoting the final state of the array after performing left rotations.

**Sample Input**

```
5 4
1 2 3 4 5
```

**Sample Output**

```
5 1 2 3 4
```

**Explanation**

When we perform left rotations, the array undergoes the following sequence of changes:

Thus, we print the array's final state as a single line of space-separated values, which is `5 1 2 3 4`
